The ball is the other sprite component. It works just like the ImageSprite except that it doesn’t contain a picture. A ball will always be a circle of a single color. You can adjust the paint color and the radius of the ball. Otherwise, a ball is exactly the same as an ImageSprite. You can even specify whether a ball rotates, and its motion will behave accordingly, although you won’t see a visual difference (a ball looks the same, regardless of its rotation).
